FUNNEL.

' Specification of Letters Patent.

Patented Oct. 19, 1920.

Application filed January 21, 1920 Serial No. 353,072.

To all whom it may concern:

Be it known that I, HARRY A. EVEN, a citizen of the United States of America, and a resident of Elkton, Brookings county, South Dakota, have invented certain new and useful Improvements in Funnels, of which the following is a specification.

My invention relates to improvements in funnels, and the object of my improvement is to supply a funnel having means for permitting escape of air from the vessel into which a liquid is being poured without 1nterference with the liquid, and said means allowing escape of allthe air in the vessel.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figures 1 and 2 are vertical central sections of said funnel taken at an angle of ninety degrees from each other, Fig. 1 showing a medial longitudinal section of the air-duct, and Fig. 2 showing the inner wall part of the air-duct removed.

Similar numerals of reference denote corresponding parts throughout the several views.

llhe funnel is of the ordinary type, having a hollow frustal body 1, and a hollow communicating frustal neck 2 of a different conical angle.

The numeral 3 denotes an air vent tube or duct mounted upon the inner surface of the funnel, extending from the upper end of the body 1 downwardly longitudinally and through the neck 2, coterminously with both, its lower end being openand its upper end closed at 4;.

A relatively large air vent orifice 6 is positioned in the wall of said body 1 near the top closure 4, and air inlet orifices 7 and 8 are positioned in the wall of the neck 2 to communicate with said duct 3'at its lower part 5 within the neck, said orifices being spaced longitudinally and the orifice 7 being of a larger area than the orifice 8.

When the neck 2 has been inserted into the bung-hole of a barrel or the open neck of a bottle or other vessel, liquid poured into the body 1 will traverse said neck without interference, as air which is forced from the vessel escapes by way of the open lower end of the duct 35, or by its orifices 7 and 8. When the open lower end of the neck 2 and duct 3-5 becomes immersed, air nevertheless, may escape from the vessel by way of the orifices 8 and 7, to the vent orifice 6, the orifice 7 being positioned to permit escape of any air at the extreme upper end of the vessel when the rising liquid has submerged the lower orifice 8.

As the conicity of the neck 2 allows its use by insertion in openings of different diameters in case such air opening is relatively small, the lower orifice 8 of the neck will serve to deliver the air contents of the vessel,. and when the capacity of the vessel is relatively small, the smaller orifice 8 will suflice for the purpose, whereas a larger orifice 7 is convenient in the more rapid evacuation of the air in vessels of larger capacity.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. A funnel having a duct mounted upon its inner surface and extending downwardly to the lower end of the neck thereof and open at the lower end, the duct being closed at its upper end, the body of the funnel having 'an orifice in its wall near the closed upper end of the duct and leading thereinto. and the neck of the funnel having longitudinally spaced orifices in its wall leading into said duct and increasing in area respectively upward.

2. A funnel having a duct mounted upon its inner surface and extending downwardly through the neck thereof, the body and frustal neck of the funnel having longitudinally spaced orifices in communication with said duct, and the orifices in said neck and body increasing in area respectively upwardly.

Signed at Elkton, S. D., this 19 day of Dec, 1919.

HARRY A. EVEN.
